BATTERY POWERED OPERATION

This device allows the propulsion unit to work during blackouts.
• The programmer has a built in charger for an NiMH 24V battery that is managed by a dedicated micro controller. The control chip adjusts
the voltage according to the condition of the connected battery.
To avoid the risk of overheating only use the battery supplied by the manufacturer SPN 999540 (999600 for the BL824). If the
battery shows signs of damage it must be replaced immediately.
The battery must only be installed/removed by qualified personnel. Used batteries must not be thrown into domestic rubbish bins
and they must be disposed of according to the local standards and regulations in force.
If LED L2 on the mother board (fig. 1-2) is 'ON' disconnect the battery immediately.
• The unit returns to normal operation once the power supply brought back on line. To use the battery again it must first be allowed to recharge.
The battery charge time with a battery in good condition can take up to a maximum of 16 hours. If the time required is greater you should
consider replacing the battery. You are however advised to replace the battery every three years.
• When the door has stopped, the controlled external devices (CTRL 24 Vdc) do not receive power in order to increase the autonomy of the
battery. When a command is received however (via radio or via cable) the programmer sends power to the controlled external devices and
checks their security status. It follows therefore that the command will be carried out (security devices at rest) with a one second delay to
give time to restore the correct operation of the devices. If after this period a security device is found to be in alarm the command will not be
carried out, power to the external devices will be cut off and the programmer will return to stand-by.
Note: If you wish to use an external receiver it must be wired to the binding posts 16-17 (fig. 1-2) otherwise a command sent via radio will not
be able to activate the gate/door.
• The self-sufficiency of the system when it is running on battery power is dependent on the ambient conditions and on the load connected
at binding posts 16-17, fig. 1-2 (power is always routed there during blackouts).
When the battery is completely flat (during blackouts) the programmer will lose the position of the door and therefore when power returns
(after the first command given) you will have to carry out the repositioning procedure (see page 80).
For this reason you should avoid leaving the electronic programmer without power for lengthy periods (more than two days).
